1. Show HN: Atlas of Space
Author: pieix
Description: Hello HN! Sharing a recent side project of mine, the Atlas of Space, that I built out to explore the Solar System.
As a long-time space nerd, I realized recently that I didn't have a good intuition on the scale, speed, and relative orientation of the celestial bodies around us. So over the break I built out a kind of spatial Wikipedia to click around and learn about planets, moons, asteroids, and other bodies orbiting the Sun.
The physics is all simulated in the browser using simple Newtonian mechanics. There's a lot left to do from here, including modeling objects in non-Keplerian orbits and replaying different spacecraft missions.
Hope you have fun clicking around, and curious to hear what I should improve next!

2. Show HN: Stagehand – an open source browser automation framework powered by AI
URL: https://github.com/browserbase/stagehand
Author: hackgician
Description: Hi HN! I’m Anirudh — longtime lurker, first time poster, and I couldn’t be more excited to show you Stagehand.
Stagehand is a TypeScript project that extends Playwright with three simple AI methods — act, extract, and observe. We’d love for you to try it out using the command below:
npx create-browser-app --example quickstart
const stagehand = new Stagehand();
await stagehand.init();
// Stagehand overrides the Playwright Page and Context classes
const { page, context } = stagehand
await page.goto("instadash.com") // Regular Playwright
// Take action on the page
await page.act({ action: "click on taqueria cazadores" })
// Extract relevant data from the page
const { price } = await page.extract({
instruction: "extract the price of the super burrito",
schema: z.object({
price: z.number()
})
})
The goal of Stagehand is twofold:
1. Make browser automations easier to write 2. Make browser automations more resilient to DOM changes.
We were super energized by what we’ve been seeing with vision-based computer use agents. We think with a browser, you can provide even richer data by leveraging the information in the DOM + a11y tree in addition to what’s rendered on the page. However, we didn’t want to go so far as to build an agent, since we wanted fine-grained control over each step that an agent can take.
Therefore, the happy medium we built was to extend the existing powerful functionalities of Playwright with simple and extensible AI APIs that return the decision-making power back to the developer at each step.
Check out our docs: https://docs.stagehand.dev
We’d love for you to join and give us feedback on Slack as well: https://stagehand.dev/slack

5. Show HN: Cardstock- Free TCG Proxy Manager for Magic, Yugioh, & Pokemon
URL: https://cardstock.denta.co
Author: adenta
Description: Trading cards are awesome, but paying $30 for some cardboard isn’t. I’ve upscaled 60,000 cards from the entire catalog of Yugioh, Magic, Pokemon, & a newer game, https://elestrals.com. I've made it easy to build a decklist, download it, and then print at home. Modern inkjet printers got really good when nobody was looking. While it’s clear they’re not real cards, the upscaling makes them look great for casual play (these are not tournament legal). It’s totally free, give it a try!
Supplies: https://cardstock.denta.co/kb/supplies Printer Settings: https://cardstock.denta.co/kb/settings Instructions: https://cardstock.denta.co/kb/instructions
Overview: I built Cardstock because I had some scripts to do this lying around, and wanted to explore the new Rails 8 magic. Kamal 2 (kamal-deploy.org/) is a game changer, SQLite in production is fine, and the database backed solid family of gems work like a charm.
Compute: I am renting a box on https://hetzner.com located in VA for $15/mo. This box has 8 gigs of ram and 2 vCPU's. This is such a deal compared to compute prices on https://render.com.
Kamal 2: This thing is amazing. Kamal gives me everything I could want (easy console access, easy shell access, a way to manage secrets, a way to see my logs, and letsencrypt support for DNS), all without a PaaS tax. The best part is the accessories feature: https://kamal-deploy.org/docs/commands/accessory/. I am running my main app with two accessories: Meilisearch(https://meilisearch.com) and OpenObserve (https://openobserve.ai). Instead of paying Algolia to host search infrastructure and sentry to host monitoring infrastructure, I’m hosting my own OSS without any fanfare.
Upscaling: To upscale the trading cards (a mandatory part of this build, scans are never high enough DPI). I am using this (https://replicate.com/nightmareai/real-esrgan) model. For upscaling every card, I've used under a hundred bucks of compute. This model was picked on a whim, but worked well enough that I didn’t compare other models.
SQLite: I used SQLite combined with Litestream (litestream.io) for my database. While I considered Postgres, I hesitated due to uncertainties around handling backups on self-hosted infrastructure. This was my first time using SQLite in production, and it was functional but with some minor annoyances. Here’s what I encountered: 1. No Default UUID Primary Key Type I had to set primary keys as strings and assign IDs manually from the application record. It’s an annoying workaround but manageable. 2. No Native Array Columns Because SQLite doesn’t support array columns, I had to use its native JSON column type, which just felt icky. If I were working with something like embeddings, this would be especially annoying, because you couldn’t enforce all the records to have the same number of dimensions. 3. Cryptic Errors At one point, a migration failed silently, leaving a cryptic error in schema.rb. The issue was resolved by rolling back the migration and redoing it, but it was once again, annoying. 4. Litestream Defaults Litestream deletes snapshots after 24 hours by default, which is far too short. When I tried to recover some data, I found it had already been deleted. Adjusting these defaults fixed the problem.
Solid Queue/Cache/Cable: The solid family of gems are all backed by the database and were a pleasure to work with. Goal was to prevent needing to reach for redis, so you have one less thing to worry about. You end up with a little more latency, which is a totally reasonable tradeoff.
Conclusions: We are moving into a post platform as a service world. Instead of buying a bespoke render.com or heroku, you just buy commodity compute and use Kamal to manage. It's like, pretty much all there, excited to see how this space matures.

7. Show HN: macOS dock pissed me off and I extended it
Author: imfrankkarro
Description: Hey HN!
So the other day macOS dock system pissed me off, completely.
I’m someone who runs 2 or 3 monitors daily: one for coding, one for chat apps, and one for design tools. But macOS only gives you a single Dock, which either stays on your main screen or auto-swaps wherever your mouse is. Complete hell.
I just wanted an easy way to keep a “chat dock” on my side monitor, a “development dock” on my center monitor, and maybe another “utilities dock” somewhere else—without messing with some complex, heavy, bloated dock replacement.
So I made one. And got feedback from my friends that it's good, and I should publish it.

9. Show HN: Weco AI Functions- a text-to-agent dev tool
URL: https://www.aifunction.com/
Author: Zhengyao
Description: Hey HN, I’m Zhengyao, one of the creators of Weco AI Functions — a platform that transforms plain-English task descriptions into reusable AI endpoints that you can use as Python functions.
We take a plain-English description of your task (e.g., “get the top 10 contributors of a given GitHub repo,” “extract phone numbers from text”) and turn it into an AI-powered endpoint with structured output.
Key points:
- Schema-first: You describe the task; we propose an output schema. Refine it if you like.
- Version control and A/B testing: Each change to your function creates a new version automatically. Compare cost, latency, or accuracy across multiple models and prompts on the same input.
- Configurable: Tweak advanced settings like chain-of-thought or temperature. Use custom internal prompts if you want deeper control.
- Monitoring: We log inputs/outputs and show aggregated stats, token counts, and cost in one place.
For Python developers, simply import aifn, and use AIFunction(<your function name>) to get a regular Python function powered by AI. That’s it. If you want to integrate the function into other languages/softwares, our REST API requires just a single POST request.
We’d appreciate any feedback or suggestions. We’re in early access, so if something’s off, let us know—this is exactly the stage where your input is super valuable. Check it out at https://aifunction.com or see our docs for more details on how it all works.
Thanks for reading. Happy to answer questions or hear your thoughts!

13. Show HN: Awra – AI-powered legislative bill analyzer
URL: https://www.awra.ai
Author: wcisco17
Description: I built Awra to solve a simple problem: understanding what bills in Congress actually mean for regular citizens.
What it does:
- Explains federal bills in plain language
- Shows state-specific impacts
- Provides cost analysis when available
- Uses AI to answer questions about any bill
I've found that while tools like ChatGPT can explain bills, they often hallucinate or work with outdated information. Awra directly fetches from Congress.gov's API and uses RAG to ensure accuracy.
Try it out: https://www.awra.ai GitHub: https://github.com/reacthor-ai/awra
Looking for feedback, particularly on accuracy and usefulness. Would love to hear from people who regularly need to understand legislation.

22. Show HN: I built a tool to help attendees connect after events
Author: Armandopdw
Description: Hi HN,
I’ve just started my solopreneur journey and recently launched my second tool.
I have had this ideas for a few years as I attended many conferences/events/retreats. I didn’t want to constantly ask for people their socials or have a bunch of business cards.
So I built AfterLinker to make it easier to stay connected after these events.
Here’s how it works:
- The organizer shares a group link.
- Participants join and add their socials/links, which are automatically shared within the group.
- Everyone can easily access each other’s socials/links.
I’d love your thoughts, feedback, or ideas for improvement!

23. Show HN: Currex, Pythonic currency calculator with real-time exchange rates
URL: https://github.com/stared/currex
Author: stared
Description: Hi!
I want to share with you an early version Currex, a Pythonic currency calculator that makes working with currencies and exchange rates simple and smoots.
I often use Python as a command-line calculator. Yet, I need to go back to Google Search to convert between currencies. So, for my own convenience, I created this library that makes it easy to add, multiply and change currencies. One of the core features is autocasting - when using a few currencies, automatically convert them to the first one.
It is intended to be used in interactive Python sessions (such as Jupyter Notebook, IPython, etc.) to get ballpark estimates of prices - e.g. when traveling, buying online, etc. Personally, I use it from the command line IPython.
It is a new package, so I'm open to suggestions.
It is NOT intended to be used in production code. Every API design decision I made was to make it as simple as possible to use in interactive sessions. Some of them are consciously at odds with a tool that could be used in a library.
EVEN MORE IMPORTANT: Never use it for any important decisions - taxes, investments, etc. There is no guarantee that the exchange rates are up-to-date and correct. Note that even major players make mistakes, e.g. a Google glitch from the last year (https://www.barrons.com/news/google-glitch-undervalues-polan...). Always use the official exchange rates.

Author: hmntyee
Description: I worked on an interesting hobby project last year. Obj-Editor is an open-source tool that helps you visualize changes to your 3D model as you edit each vertex and face of the model.
Back when I was studying how 3D models are stored in files, I came across the problem of having to edit a simple, human-readable .obj on a text editor and start up blender for every iteration to see my changes. So I built this tool on Unity that helps you edit the raw .obj and see changes on your mesh live on side-by-side screens.
I have since grown as a dev and know that many fixes and other essential features are required to see this tool going anywhere, but I thought it's a cool little thing to showcase on here.

Description: Hey HN, I was searching for the code snippet button in Gmail one day and turns out it just didn't exist! So I built it with this Chrome extension.
One of the underrated features of Slack or Discord is the code snippet button, which quickly formats code using strong styling.
These features never made their way over to mainstream email clients. As email is still used heavily for external communications, this is an obvious blind spot.
Blocky is ideal for customer success teams, help desks, students, and engineers who need to send small code snippets over email. Usually stuff that wouldn't bother with a Github commit.

these opportunities never reach to mass audience and most importantly us.
sniff is collecting massive data every hour
The database is connected to an AI intelligent model to make perfect match
You can login to sniff and prompt "hi i am good with excel, i can design in figma and i can write well. is there any opportunity of my interest posted this week?"
Sniff will find the best match, and best alternative.
It also looks for intent of user, imagine a user posted "ah man, my app crashed again, F", it might seem like a blabber, but Sniff sees this as an opportunity for web developers, system architects, DS people, people in network etc. you get my point
Sniff is growing fast, and people lovin it.

33. Show HN: pay-respects – RIP command errors and keep yourself in the flow
URL: https://github.com/iffse/pay-respects
Author: iffse
Description: pay-respects is a command-line utility written in Rust that tries to fix the previous command, by simply pressing F. (From the meme "Press F to pay respects").
Don't let Rust scares you. You don't even need to know how to code in order to add a new rule for suggesting fixes. Even with zero-compromises to performance, as they can be evaluated to Rust code during compilation.
Rules can be added at runtime if you don't want to recompile. The entire system is even modular, allowing to write rules in any languages that are most comfortable to you.
You can still get potential fixes even when there is no rule for the specific case you are facing thanks to the AI integration (API key included so you can try it out of the box).
The project started long ago when in a group chat people complained about the speed of thefuck (myself included). Although thefuck is the very first pioneer for tools like this, it's very slow (slower than typing sudo !!) and creates weird suggestions lately, making it completely useless.
At the end of that day, I ended up with a prototype with procedural macros to generate rules from a TOML file. I took this approach as I don't want to compromise performance, nor I want to make it hard to contribute because Rust is "hard" and takes time to write the code due to its verbose nature.
Less than a week, the project is basically done, supporting all major shells and solves all situations that I used to run into. It worked so well that there wasn't a single commit or bug report for more than a year.
You might ask why I am promoting this project now. Apparently thefuck stopped working some months ago with new Python versions and no maintainer is working to fix it. Many people who searched for an alternative have reached to my project. The tool itself works well, and people asked me to package into the distribution they use. That is not easy for me, as I don't have access to their upstream, nor I have the social network to contact respective package maintainers.
At the time of writing, pay-respects is not the first project that tries to substitute thefuck, nor the last one. But rather a unique one that stands out from all others because the approach is different from the ground up. (To be honest, I didn't even bother to study other projects before creating the project. There were only "speed" and "ease" in my mind).

WebGPU is cool. It's exciting to me to see these things working with no download.

40. Show HN: LeetCode with Spaced Repetition
URL: https://www.ankicode.com/
Author: gordbegli
Description: Solve questions in a LeetCode like style. You’ll be shown them again at a later date determined by your pass/fail history and when you’ve used the LLM integration for help.
NeetCode’s great tutorials are embedded. AnkiCode also similarly introduces basic concepts before those that build upon them.
Enjoy!
The source code is public. Click on the logo to see it. I was trying to contribute to Tinygrad recently and tried a similar low loc style in this codebase, which may be jarring.

44. Show HN: FormML – A DSL for building forms (like Prisma but for forms)
URL: https://github.com/formml/formml
Author: jindongz
Description: Over the years, I’ve encountered many challenges while building complex forms from scratch - challenges that I believe are common, difficult, and yet often overlooked.
While there are many awesome tools in the ecosystem for building basic forms, like Formik and React Hook Form, there isn't yet a serious solution (to my knowledge) that specifically addresses these pain points of complex ones.
Finally, this led me to come up with my own solution FormML (Form Modeling Language) that specifically addresses "enterprise-level" form needs.
Looking forward to your thoughts and feedback!

48. Show HN: 300 Pages of AI-Driven Insights on Growth and Learning
URL: https://2472241684911.gumroad.com/l/whathow
Author: anon012012
Description: Hi HN,
GPT has reached a point where it can contribute meaningful insights—even writing books that are worth reading.
I’ve spent time (and a bit of money) systematically extracting deep insights (from the latest GPT-o1) on self-improvement in general and self-education in our rapidly changing world. The result is a free 300-page ebook titled What & How: Evolving in the Age of GPT. It explores what to know, what to do, and how to grow during these transformative times.
Here’s a sample chapter (~ randomly selected):

And here’s the table of contents:
If you don't want to use Gumroad, the PDF is also free on Github:
https://github.com/Lywald/whathow/tree/main
I’m self-publishing paperback version on Amazon soon! For myself and maybe others. Before I print, I’d love some feedback!
For the curious, this is the prompt I used (it's actually fairly simple):
"""You are a brilliant writer and thinker. You write plain and clearly but juicy knowledge. You DO NOT write common sense, obvious stuff. Only low-noise, high signal. Keep on pounding the user's mind with high level abstractions, and precise details and tips, and methodologies. IT should be mindblowing, and not ordinary. You think very deeply about what you are writing. We are writing an ebook together. """

49. Show HN: StayWithMe – Make your parents digitally immortal
URL: #
Author: loboda_ro
Description: Hi HN,
Roman and Oleg here, and we want to share the StayWithMe project with you all! We build software that can make people digitally immortal. You upload your chat history from What’s App or Telegram together with a short voice recording of the person you want to clone on our website. We process your data and you get a phone number that you can call and talk to the person you cloned. you can clone yourself.
Why We Built This
Roman lost his father to cancer when he was 16, a loss that changed his life forever. His father was the person he could talk to about anything, and his death left a deep gap. It took him years to recover. But, we realized that with the technologies and skills we’ve gained, we could create a digital version of his father using old WhatsApp messages. This project is our way of keeping his memory alive and helping Roman reconnect with the bond he shared with his father.
How It Works
You can either call Roman’s clone, or fill out the form to clone a person you know (yourself as well). In the form you will have to put in basic info about the person you are cloning, upload exported chat history (whatsapp or telegram) and mp3 voice sample of how they normally talk.
After you uploaded everything the website will prompt you to select the person (out of two present in chat history) who you want to clone. It will appear on the profile page as creation in process.
Then you will have to wait for about 30 minutes (might be up to a couple of hours depending on how large your chat history is) until it will be created. Now you will activate it by clicking on it and putting your phone number you will be calling from.
When you’ll see a persona in green, meaning it is activated for usage, call the phone number provided on the profile page of the website above the list of your personas.
Tech Stack: Voice - ElevenLabs.io Facts Extraction - Kor python library LLM - GPT 4o Phone Call - Twilio Transcription - Deepgram
Demo Link: staywithme.io
all instructions are in the how it works section.
What We’d Love Feedback On
We’d love to hear your thoughts, feedback, or any questions you have! We’ll be around to respond to comments and discuss further.
What’s Next?
To help people leave a meaningful legacy, we plan to record short interviews with them. These interviews will later be used to create a digital version of the person - not just based on chat history.
Thank you for taking the time to check it out, and we are looking forward to your insights!

50. Show HN: I Built an AI-Powered Study Tool That Makes Learning Stick
Author: bukunmiadewale3
Description: Like many students, I struggled with remembering what I studied. I’d read, highlight, and take notes—only to forget everything a week later. Turns out, passive learning doesn’t work.
What does work? Active recall. Science backs it: testing yourself strengthens memory better than rereading.
So, I built SyncStudy—an AI-powered tool that generates quizzes, flashcards, and study challenges from any text, helping you master concepts faster. No more cramming. No more wasted hours. Just better learning, smarter retention.
It’s free to try, and I’d love feedback from the HN community!

53. Show HN: Could I have done better? (investment tool)
URL: https://github.com/onescales/investment-comparison-tool
Author: onescales
Description: In the last 2-3 years i've spent a lot of time to understand investing better and occasionally sample and check different stocks and crypto and see how it coompares.
I built a very simple tool to see if my investments could be improved upon. In short, if i would have placed the same amount of money in a different stock or crypto for example, would i have done better?
It's open source and in-browser (using local storage), meaning investment data stays private in your browser between you and your browser (yourself). Everything is in 1 html file only which you can use or copy and change yourself. Lastly, in order to get stock and crypto prices, it does use 2 api's (Twelve Data & Alpha Vantage)
Hope it's helpful for you guys and let me know if you have any suggestions.
